Here is my question. My 11 year old son recently collected caddie bibs at the RBC Heritage Golf Tournament on HHI SC. While he was there both days on Saturday and Sunday, several Titleist golf ball users were kind enough to throw him a ball which the player used in the event. I will not include names of players but you can guess who some were.
My question is this, I noticed on some of the PROV1X balls there was a + sign after PROV1X and also a "dot" after the PROV1X stamping. What does the plus sign and the dot represent and how does it alter the ball?
